I can't say what the clicking sound might be. I assume you lubed the regulators with grease before putting them in. I hate to suggest it but you might pull it back out and have a look at what it's doing. I may have a pair of manual parallel arm regulators laying around if you decide to replace yours.
As for the weight issue, let me say that it's a little complicated. Electric regulators are heavier than manual ones, but you have to compare like units (from the same era). For instance:
Early electric motors are heavier than later ones.
Parallel arm regulators (either type) are heavier than cross arm regulators.
Targa and cabriolet regulators are heavier than those from a coupe.
Later glass supports are slightly heavier than early ones.
As an example, I'm replacing the older style electric regulators from a 77 Carrera 3.0 coupe with manual cross arm regulators. Including the different glass supports, switches and wiring, my total weight savings will be around 7 lbs. My guess is the 2 lbs. quoted above is per regulator.
